MACHINE FOR FORMING ARTIFICIAL-FUEL BLOCKS- Specification of LettersPatent.

Be it known that I, MICHAEL M. KLINE, a

T at whom, it may concern: l

citizen of the United States, residing at St. Louis, Missouri, haveinvented a certain new and useful Improvementv in Machines for FormingArtificial-Fuel Blocks, of which l the following is a full, clear, andexact description, such as will enable others skilled. in the art towhich it appertains to make and use the same, reference being had to theaccompanying drawings, forming part of this specification, in which-Figure l is a front elevation of a portion of a machine embodying thefeatures of my invention. Fig. 2 is a top plan view of the plate whichcarries the upper dies. Fig. 8 is a plan View of the underneath side ofthe plate which carries the lower dies. Fig. 4 is a top plan view of themold member. Fig. 5 is a top plan view of the lower-die-carrying memberwith the plate shown in Fig. 3 re' moved. Fig. 6 is a perspective viewof one of the lower dies. Fig. 7 is a erspective view of one of theupper dies, and Fig. 8 is a view of the artificial-fuel block which mymachine is designed to form.

This invention relates to compressing-machines, and has for its objectto provide a machine of novel construction for forming artificial-fuelblocks.

Referring to the drawings which represent the preferred form of myinvention, 1 designates the frame of the machine, and 2 desig nates aplate or member carried by the frame and provided with a plurality ofopenings 3 to receive the material from which the fuelblock is formed. Amember 4: is arranged above the mold member 2 and carries a plurality ofdies 5, which are adapted to project into the openings in the member 2.A member 6 is arranged beneath the mold member 2 and also carries aplurality of dies 7, which project into the openings in the member 2,suitable means being provided for actuating the upper and lower diecarrying members to cause said dies to move toward and from each otherto compress the material placed in the openings in the mold member.

The substance from which the fuel-blocks are formed consists principallyof pulverized slack coal, and to attain the desired results in thefinished product it is necessary that the dies which compress saidmaterial into completed form should be heated. To this end I haveprovided the upper and lower die carrying members with chambers 8, whichreceive a heating fluid, so that heat will be imparted to the diescarried thereby. Preferably steam is used as the heating medium but itwill of course be understood that hot water could be substitutedtherefor or the dies could be electrically heated without departing fromthe spirit of my invention.

In the machine herein shown, which represents the preferred form of myinvention, the steam is supplied to the die-carrying members by means offlexible tubes 9, leading from suitable supply-pipes 10 and entering thechambers 8. The upper dies 5, which are preferably solid and ofcylindrical form, as shown in Fig. 7 of the drawings, are connected byheaded taps 1,1 to a plate 12, which is connected to theupper-die-carrying member by screws 13, said plate 12 being providedwith recesses 14 to receive the heads of the taps 11. The lower dies 7are also of cylindrical form, as shown in Fig. 6, but are provided withlongitudinal bores 15, as shown in Fig. 1, and are connected to a plate16 by headed nipples 17. Said plate 16 is fastened by screws 18 to thelower-die-carrying member 6, and said plate is provided on itsunderneath face with recesses 19, which are connected with each other byconduits or grooves 20, formed in the underneath face of plate 16, thusforming passageways for the circulation of the heating fluid.

As shown in Figsl and 5, the lower-diecarrying member 6 is provided withports 21, leading from the steam-chamber 8 therein, and when the plate16 is in operative position said ports register with some of therecesses 19 or grooves 20 in the underneath face of the plate 16, sothat the steam in the chamber of the lower-die-carrying member cancirculate through the plate 16, and thus pass up into the bores of thedies 7 to heat same, the heads of the nipples 17, which hold said diesinposition, not being large enough to occupy all of the s ace of therecesses 19.

Preferably the upper and lower dies are provided with concave faces, asI desire to make the fuel-block B of the form shown in Fig. 8. I

In operation the material blocks are formed is placed in the openings inthe mold-plate 2, the lower dies 7 normally projecting into saidopenings, and thus forming bottoms therefor. The upper and lower diecarrying members are then moved from which the toward each other tobring the dies into the position shown in Fig. 1 to firmly compress thematerial, and thus produce an artificialfuel block B of the form shownin Fig. 8, the block when finished being ejected from the molds afterthe dies have been separated, preferably by moving the lower dies 1U.wardly until their ends extend approximate y flush with the upper faceof the mold-plate 2.

Having thus described my invention, what I claim as new, and desire tosecure by Let ters Patent, is

1. A machine for forming artificial-fuel blocks, comprising adie-carrying member provided with a chamber for receiving a heatingfluid, means for supplying a heating fluid to said chamber, a plateconnected to said die-carrying member and provided on 'its underneathface with conduits or passage-ways, ports leading from the chamber, inthe die-carrying member to said conduits, dies mounted on the upper faceof said plate and provided with central bores, and nipples dies inposition and for esfor holding said tablishing communication between thebores in said dies and the conduits in the plate; substantially asdescribed.

2. A machine for forming artificial-fuel blocks, comprising adie-carrying member receiving a heating fluid, a flexible tube extendinginto said chamber for supplying a heating fluid thereto, a plateconnected to said die-carrying member and rovided on its underneath facewith a plura ity of circular recesses, and grooves connecting saidrec'esses together to form passage-ways for the circulation of theheating fluid, ports leading from the chamber in the die-carrying memberto points in said passage-way, dies carried by said plate and providedwith central bores, and headed nipples for securing said dies to theplate, the heads of said nipples resting in the circular recesses in theplate and being of less dimensions than said recesses; substantially asdescribed.

In testimony whereof Ihereunto affix my signature, in the presence oftwo witnesses, this 20th day of July, 1906.
